  • a syringe 200 including, for example, a rearward flange 220, to injector 10.
  • rearward flange 220 has a generally circular shape with straight or flattened, opposing sides 222a and 222b.
  • advancing piston 40 in a forward direction applies a motive force to a plunger 210 (see, for example, Figure 7C) within syringe 200 through passage 110 in adapter 100 to advance syringe plunger 210 forward within syringe 200, thereby forcing contrast medium in syringe 200 out of syringe tip 250 into the fluid path to the patient.
  • a plunger 210 see, for example, Figure 7C
  • syringe 200 is first aligned with passage 110 in adapter 100.

  • movement of syringe 200 to the rear can involve the attachment of a syringe plunger 210 to a plunger adapter 800 (see Figure 8E) via, for example, rotating syringe 200 to thread syringe plunger 210 onto plunger adapter 800.
  • retaining member 120 is slid upward or radially inward to a closed or secure position as illustrated in Figure 2C .
  • advancing piston 40 in a forward direction will cause the forward surface of syringe flange 220 to abut the rearward surfaces of abutment members 122a and 122b of retaining member 120 as well as the rearward surface of lower abutment member 122c (which connects abutment member 122a and 122b to form a generally U-shaped abutment member in retaining member 120), thereby retaining syringe 200 within adapter 100.
  • Adapter 100 can also include a rear abutment surface 140 to assist in properly positioning syringe 200 within adapter 100. Should piston 40 be retracted, the rear surface of syringe flange 220 abuts rear abutment surface 140 to prevent syringe 200 from moving rearward within adapter 100.
  • FIG. 3A-3C Another embodiment of an adapter 500 of the present invention is illustrated in Figures 3A-3C .

  • syringe 200 is moved rearward until flange 220 is positioned to the rear of U-shaped abutment members 522a and 522b of sliding retaining members 520a and 520b, respectively.
  • rearward movement of syringe 200 can include attachment (for example, by rotation relative thereto) of syringe plunger 210 to plunger adapter 800.
  • Adapter 500 can also include a rear abutment surface 540.
  • the two sliding retaining members 520a and 520b of adapter 500 fully engage or encompass rear flange 220 of syringe 200 (that is, U-shaped abutment members 522a and 522b contact the forward surface of flange 220 around the entire perimeter of flange 220). Because the contact is symmetrical about the axis of syringe 200, advancing piston 40 does not result in bending moments upon syringe 200, as described above for adapter 400.
  • full contact around the perimeter of syringe flange 220 by adapter 500 distributes forces over the entirety of syringe flange 220 and thus enables syringe flange 220 to endure greater force without distortion or failure as compared to the case in which only part of flange 220 is contacted by a retaining or abutment member.
  • full contact with syringe flange 220 enables manufacture of syringe 200 from materials that might fail under conditions of only partial contact of a retaining member with syringe flange 220.

  • Contact of flange 220 with contact member 732 and further rearward movement of syringe 200 causes second retaining member 730 to pivot or rock rearward about axis A' so that second retaining member 730 becomes generally vertically oriented (generally perpendicular to axis A") and generally in plane with retaining member 720.

Abstract

L'invention concerne une interface ou un adaptateur de seringue comprenant un premier élément de retenue qui pivote autour d'un axe généralement perpendiculaire et décalé par rapport à l'axe d'un piston d'injecteur lorsque l'interface est reliée à l'injecteur. Le premier élément pivote vers l'arrière pour s'enclencher avec une partie de la bride de seringue. L'interface comprend en outre un second élément de retenue qui coulisse dans un passage de l'interface, selon une direction généralement perpendiculaire à l'axe du piston lorsque l'interface est reliée à l'injecteur, aux fins d'enclenchement avec une partie de la bride de seringue. De préférence, les deux éléments de retenue coopèrent pour s'enclencher avec la bride de seringue sur tout le périmètre de cette bride. De préférence, le premier élément est contraint en position ouverte. L'interface peut également comprendre une partie arrière à mécanisme de raccordement entre l'interface et l'injecteur.
